C U LTIVATOR.

SPECIFICATION forming part of Letters Patent No. 492,509, dated February 28, 1893. Application filed .Tuly 16, 1892. Serial No. 440,229. (No model.)

To all whom t may concern,.-

Beit known that I, APPLETON R. DAVIS, a citizen of the United States, residing at Valley, in the county of Douglas and State of Nebraska, have invented a new and useful Culivator, of which the following is a specificaion.

My invention relates to improvements in cultivators, and refers particularly to that class known as two-row cultivators, the obj ect of the improvement being to provide a device of this kind which may be operated either riding or Walkin g.

A further object of my improvement is to provide simple and direct means for moving the shovels laterally to suit irregularities in the rows.

A further object of the improvement is to provide means for adjusting the various parts of the machine to accommodate different widths of rows and different distances between rows.

Further object of my improvement will appear hereinafter in the description, wherein the detail construction and arrangement of parts is explained in connection with the drawings, and the novelty of my invention will be particularly pointe-d out in the claims hereto appended.

In the drawings: Figure l is a perspective view of a culti'vator embodying my invention. Fig. 2 is a similar view with the riding-attachment removed. Fig. 3 is a plan view of the latter, partly broken away, and showing in dotted lines the extreme inner positions of the shovel-frames. Figs. 4 and 5 are detail views.

A designates the main-frame of the culti-V wardly divergent braces, g g and g g', ex-` tend from the tongues to the outer and inner spindles, respectively, thus bracing the lower ends of the hangers and binding the parts of the main-frame together. The hang? ers are secured to the underside of the crossbeam by means of keepers,`H H, which enable the hangers to be laterally adjusted.

The shovel-frames, K K, consist of the arches, K', having the horizontal off-sets, k It, to which are secured the shovel stocks, 7e lo', and k, bearing the ordinary shovels, k". The inner shovel-stock, designated by the letter, It, in each frame, is provided with an olfset, to which the shovel is attached, the object of such off-set being to bring the shovel closer to the center of the machine. One of the stocks, lt, is longer than the other to enable them to overlap when the shovel frames are swung inward, as indicated by the dotted lines in Fig. 3.

The shovel frames are connected, by means of connecting bars, L L, to swivel-blocks, M M, which are mounted on the Ltbove mentioned spindles upon the lower ends of the hangers, said conneetingbar being pivoted to theshovel frames and also to the swivel blocks, whereby said frames are capable of free lateral swing. Handles, N N, are secured to the rear sides of the arches for the use of the operator when walking and eyes, O O, are provided at the tops of the arches to engage hooks, O O', carried by the rearwardly projecting supports, P P, carried by the main-frame and secured tothe cross beam and transverse bar. The swivel-blocks allow the shovel frames, or either of them, to be elevated temporarily or permanently.

My cultivator is designed for three horses, one to be arranged between the tongues to walk between the rows, and the others to be attached outside the tongues to walk outside the rows.

To equalize the draft of the horses I em ploy the Whittie-trees, Q Q, pivoted at points one third of theirlengths from their outer ends to the main-frame, vertical draft bars, Q Q', attached at their upper ends, respectively, to the extremities of the Whittle-trees, and having their lower ends connected to the spindles, above described, by the links, q q, and single-trees, q q attached to the centers of the draft-bars. The two inner draft-bars are connected to the single-tree, shown, by the short chain, q, passing around a pulley on the single-tree.

l The riding-frame consists of a centerbeam, R, carrying, at its rear end a supporting wheel, r, and at an intermediate point thesea't, r', the transverse beam, R', attached at its center' to the front end of the center beam, and the forwardly divergent bars, R R, provided at their front ends with eyes, r r, to

engage hooks, fr" fr", on the rear side of the cross-beam ofA the main-frame. Rock-shafts, Sl S, mounted upon the transverse beam are provided with arms, s s which are connected by chains, S S', to the ends of the arched shovel-frames, whereby, by operating said rock-shafts the shovel frames may be ele# vat'ed or lowered. Operating levers, T T, are attached to the rock-shafts and co-act with toothed arcs, H, whereby the shovel frames may be locked in their elevated position.

From the/above `description it will be ap# parent that the riding-frame may be'detached from the main-frame when it is desired to operate the cultivator by hand, or walking.

Stirru ps, U U, are attached to the inner ends of the shovel-frames to receive the feet of the operator, and if necessary the latter may raise f the frames by means of said stirrups.

The joints between the front ends of the connecting-bars and the swivel-blocks are formed by the vertical bolts p p, which take in any one of a series of perforations, p p', in said blocks. Thus, the shovel frames, in addition to being capable of vertical and lat,- eral movement, bythe universal connections provided therefor, are capable of lateral adjustment with relation to the main-frame.

Also, blocks V V which are attached to the 2 It will`be noted, furthermore, that in the alignment of the rows, or one of them, the shovels maintain their 'positions with their faces squarely to the front. They are not turned at an angle by their lateral movement. It will be noted, furthermore, that the looped-hangers, above described, raise the maine-frame Well up out of the way of corn or other produce growing in the rows, and the arched shovel-frames and hangers span the rows, respectively, and thus allow short shovel-stocks to be employed and also bring a horizontal draft upon the shovel frames from the main-frame. The lower ends of the draft bars are connected to the spindles through which the draft upon the shovel-frames is conveyed. Y I Y Having thus described my invention, what il claim, and desire to secure by Letters Patent of the Unitedl States, is A l. In a cultivator, thecombinatiorwh the main-frame, of the shovel-frames,- swivelblocks carried by the main-frame, and connecting bars pivoted at their opposite endsto the shovel-frames and said swivelblocks,.sub

2. In a cultivator, the combination with" the main-frame havinga cross-beam, as described, :of the laterally adjustable hangers secured to said cross-beam, swivel-blocks'l Vmounted upon spindles at the lower eXtremitli'es'of said oted connecting-bars with said swivel-blocks, substantially as specied. v

3. In a cultivator, the combinationwith the main-frame, of the shovelframes, secured by pivotal connecting-bars to the mainy frame, `and comprising the arches having off-sets 7o, and the laterally adjustable blocks V secured to said off-sets and carrying'th'e shovel-stocks, substantially as speciiied. l y 4.
